3 Claims.

' IThis invention relates to concrete forms and more particularly to a metal bracket adapted to be :secured tothe vertical studs of a woodenconcrete form for supporting a pair of horizontal waler studs in vertically spaced position therein.

In setting up wooden concrete forms, two vertical walls of wooden boards are commonly employed between which the concrete is poured. These boards are usually nailed at spaced intervals to vertical studs (2 x 4s) to which the horizontal waler studs are nailed.

In the present invention, instead of nailing the waler studs to the vertical studs, provision is made of a plurality of angular metal brackets which are attached to said vertical studs. The brackets have side anges on which the pairs of superimposed horizontal waler studs are supported. Each bracket is provided with a spreader arm which serves to space apart the waler studs vertically sufficiently to embrace a plurality of horizontal transverse metal spacer rods which are adapted to be embedded in the concrete.

One object of the present invention is to provide a waler bracket of the above nature having a pivoted spreader arm located between each pair of horizontal studs supported by said bracket, and in which said spreader arm has a pair of vertical oppositely-extending pins adapted to penetrate the adjacent surfaces of the horizontal waler studs and thus eliminate the necessity oi' driving nails to hold said horizontal studs to said vertical studs.

A further object is to provide a device of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, easy to assemble and knock down, compact, ornamental in appearance, which may be used over and over again, and which will be very efficient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawing one form in which the invention may conveniently be embodied in practice.

In the drawing,

Fig. 1 represents a perspective view of a wooden concrete form showing two of the vertical studs, the pair of concrete retaining walls, one pair of horizontal waler studs, and a pair of waler brackets for supporting the same.

Fig. 2 is a fragmentary end view of the same, shown partly in section, looking in the direction of the arrow 2 of Fig. 1.

Fig. 3 is a fragmentary top plan view looking downwardly in the direction of the arrow 3 of Fig. 1.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numerals I0 and II indicate a pair of parallel walls of wooden boards which serve to retain the concrete when poured therebetween until it has set. In order to support the boards I0 and II and hold them rigidly in assembled position, provision is made of a plurality of pairs of vertical studs I2, I3, to which said boards are secured as by nails (not shown).

In order to support the pairs of horizontal waler studs I8, I9, and I8a, I9a upon the vertical studs I2, I3, provision is made of a plurality of pairs of substantially L-shaped metal supporting brackets indicated by the numerals I4, I5, and having horizontal outer anges I6, I'I bent downwardly from the metal of said brackets. Each pair of horizontal waler studs I8, I9 are adapted to be supported a definite distance apart (such as 3A, inch) by means of a plurality of metal spacer rods 2B (only one being shown) which pass through the concrete and are embedded therein when the latter has set. The spacer rods 2|) are provided on their opposite ends with flanged heads 2|, 22, which hold key plates 22a for embracing the outer edges of the waler studs I8, I8a, I9, I9a, respectively.

The waler studs are also spaced apart by means of spreader arms 23, 23a which are provided with vertical end pins 24, 24a. which are preferably spotwelded to the spreader arms 23, 23a. The pins 24, 24a are adapted to be driven into the adjacent surfaces of the waler studs I8, I8a, I9, Illa, so as to hold said studs spaced apart at the predetermined distances.

The spreader arms 23, 23a are pivotally mounted on the waler brackets I4, I5 by means of headed pins 25, 25a which are embraced by vertical slots 26, 26a formed in the upper narrow vertical arms 2l, 21a, of said metal waler supporting brackets. The arms 2l, 21a are secured to the vertical studs I2, I3, as by sets of three attaching nails 28, 29, 30, and 28a, 29a, 35a, respectively.

The shelves I6, I'I of the waler brackets I4, I5 are adapted to be reinforced by inclined sections 3l, 3Ia connecting the outer portions of said shelves to the bottom portions of the waler bracket,

One advantage of the present invention is that it is unnecessary to attach the waler studs to the vertical studs by the use of nails, but said studs may be easily attached in a denite spaced relationship upon the vertical studs by means of the spreader arms 23, 23a of the waler brackets I4, I 5.

3 A further advantage of this invention is that much time is saved in setting up the forms and the operation of disassembling the forms is also l greatly facilitated.

While there has been disclosed in this specication one form in which the invention may be embodied, it is to be understood that this form is shown for the purposes of illustration only, and that the invention is not to be limited to the specific disclosure; loutmay be ,modified and embodied in various other-forms without departing from its spirit. In short the invention includes all the modications and embodiments coming within the scope of the following-claims, Y

Having thus fully described the invention, what is claimed as new, and for which it is desired `to secure Letters Patent, is:

1. In a bracket for separating a pair of horizontal vertically spaced upper and lowerwaler studs of a concrete form, a vertical plate, means teseere said; plete-,LQ a verticaltstud attahed to @wooden-concrete retti-nirewally, a; horizontal Qsnel@iniigml with .said pletaand @Spreader arm 4 mounted on said plate on a horizontal pivot pin located above the top of said lower Wale-r stud, for supporting said upper Waler stud in spaced relation from said lower Waler stud.

2. The invention as defined in claim 1, in which said pivot pin is adjustably mounted in a vertical slot in said plate.

3. The invention as dened in claim l, in which said spreader arm has upstanding and depending pointed ends for(A penetrating the fadjacent surfaces of the waler studs.
